An Analysis Of Shoreline Development Risk For Secondary Dune Systems In Tidewater Virginia With Associated Management Recommendations, Lyle M. Varnell, C. Scott Hardaway Jr.
An Analysis Of Shoreline Development Risk For Secondary Dune Systems In Tidewater Virginia With Associated Management Recommendations, Lyle M. Varnell, C. Scott Hardaway Jr.
Reports
This project was done in response to concerns by environmental resource managers of historic and potential adverse impacts to Virginia’s secondary dune ecosystems. Virginia environmental regulatory programs have little decision-making authority over the use of secondary dunes as these areas are not included in the Coastal Primary Sand Dune Act (the Dunes Act). These areas function as estuarine edge habitat and provide natural upland erosion control, and are thus valuable to estuarine and coastal plain fauna and adjacent upland property owners.

Monitoring Relative Abundance Of American Shad In Virginia’S Rivers 2001 Annual Report, John E. Olney, Kristin L. Maki
Reports
Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio, spawning …

Virginia’S Coastal Program: Strategic Mapping Of Management Goals, Jennifer Newton, Pamela Mason, Carl Hershner
Virginia’S Coastal Program: Strategic Mapping Of Management Goals, Jennifer Newton, Pamela Mason, Carl Hershner
Reports
Virginia’s Coastal Resources Management Program is a networked program bringing together the activities of many state agencies and institutions to achieve the overarching mission of coastal zone management. The Program’s objectives were originally set out in a series of 25 goals in the 1986 Executive Order (see Appendix B) that established the Program for the Commonwealth under the federal Coastal Zone Management Act. Beginning in May of 1999, representatives of the Virginia state agencies involved with the networked Coastal Program attended a series of meetings to develop logic maps of these twenty-five goals. This document represents the final results of …

Status Of The Major Oyster Diseases In Virginia 2001 A Summary Of The Annual Monitoring Program, Lisa M. Ragone Calvo, Eugene M. Burreson
Reports
Thirty-nine oyster populations were surveyed for disease in fall 2001. Perkinsus marinus was found in all areas sampled and prevalence exceeded 90% at all but 5 sample locations. In the James River P. marinus prevalence ranged from 88-100% at Deepwater Shoal, Horsehead Rock, Point of Shoals, Wreck Shoal, Mulberry Point, Swash, Long Shoal, and Dry Shoal. A lower prevalence was observed down river at Thomas Rock, 72%, and at Nansemond Ridge, 12%. The extremely low prevalence at Nansemond Ridge is likely age and density related; the oyster population was primarily comprised of spat; few small to market oysters were present …

Historical Overview Of Tampa Bay Water Quality And Seagrass Issues And Trends, J.O. R. Johansson
Historical Overview Of Tampa Bay Water Quality And Seagrass Issues And Trends, J.O. R. Johansson
Reports
Historical (pre-1930s) seagrass meadows in Tampa Bay are believed to have covered 31,000 ha of the shallow bay bottom. Later, impacts to the bay from increasing population and industrial development of the Tampa Bay area have resulted in large seagrass losses. By 1982, approximately 8,800 ha of seagrass remained. Since 1982, Tampa Bay seagrass monitoring programs have recorded a reversal in the trend of seagrass loss, with the baywide seagrass cover increasing from 9,420 ha in 1988 to 10,890 ha in 1997. However, between 1997 and 1999 the trend again reversed with substantial losses recorded, specifically in the Old Tampa …

Historical And Current Observations On Macroalgae In The Hillsborough Bay Estuary, J.O.R. Johansson
Reports
To improve the understanding of macroalgae dynamics it was recommended that long-term monitoring of the macroalgae in the bay be initiated. Subsequently, the City of Tampa initiated a Hillsborough Bay macroalgae monitoring program that since 1986 has been providing consistent monthly biomass and species composition information from five fixed transects. In addition to the transect monitoring, low level aerial observations are conducted on a near monthly schedule for estimations of bay-wide macroalgae and seagrass coverage. Results indicate that the annual bay-wide macroalgae coverage has decreased near steadily from about 300ha in the late 1980's to less than 30ha since 1997.

Stated Preference Methods For Environmental Management : Recreational Summer Flounder Angling In The Northeastern United States, Robert L. Hicks
Stated Preference Methods For Environmental Management : Recreational Summer Flounder Angling In The Northeastern United States, Robert L. Hicks
Reports
Environmental managers are becoming increasingly aware that environmental policies must be crafted in a way that incorporates the human dimensions of the ecosystem. Failure to incorporate stakeholder preferences into management measures can lead to policies that fail because people’s preferences, motivations, and behavior concerning their use of the environment were not properly considered even if defensible natural science approaches were incorporated in the management decision. In this paper, we present a new method for quantifying angler preferences for fisheries management. The method, called the Stated Preference Discrete Choice Technique (SPDC) (Louviere et. al) is a particular form of conjoint analysis, …
